Hi, I am not sure if I am in the right forum regarding setting up the load balancer with JBoss4.2.0 GA.
I have clearly followed the step by step procedure mentioned in the following link: http://www.jboss.org/wiki/Wiki.jsp?page=UsingMod_jk1.2WithJBoss Configuration files and properties files required to set up are: 1. httpd.conf 2. mod-jk.conf 3. workers.properties 4. uriworkermap.properties All of the above files are placed under anonymous wrote : apache2/conf 5. server.xml placed underanonymous wrote : default/deploy/conf/jbossweb-tomcat55.sar 6. jboss-service.xml placed under anonymous wrote : default/deploy/conf/jbossweb-tomcat55.sar 1. httpd.conf Added the following piece to the existing file under the mensioned dir: | # Include mod_jk configuration file | Include conf/mod-jk.conf | | # Configure mod_jk | # | JkWorkersFile conf/workers.properties | JkLogFile logs/mod_jk.log | JkLogLevel debug | | JkMount /web-console/* node1 | JkMount /jmx-console/* node1 | JkMount /mambo/* node1 | JkMount /*.jsp node1 | JkMount /servlet/* node1 | | LoadModule jk_module modules/mod_jk.so | 2. mod-jk.conf | # Load mod_jk module | # Specify the filename of the mod_jk lib | LoadModule jk_module modules/mod_jk.so | | # Where to find workers.properties | JkWorkersFile conf/workers.properties | | # Where to put jk logs | JkLogFile logs/mod_jk.log | | # Set the jk log level [debug/error/info] | JkLogLevel debug | | # Select the log format | JkLogStampFormat "[%a %b %d %H:%M:%S %Y]" | | # JkOptions indicates to send SSK KEY SIZE | # Note: Changed from +ForwardURICompat. | # See http://tomcat.apache.org/security-jk.html | JkOptions +ForwardKeySize +ForwardURICompatUnparsed -ForwardDirectories | | # JkRequestLogFormat | JkRequestLogFormat "%w %V %T" | | # Mount your applications | JkMount /web-console/* loadbalancer | JkMount /jmx-console/* loadbalancer | JkMount /mambo/* loadbalancer | | # You can use external file for mount points. | # It will be checked for updates each 60 seconds. | # The format of the file is: /url=worker | # /examples/*=loadbalancer | JkMountFile conf/uriworkermap.properties | | # Add shared memory. | # This directive is present with 1.2.10 and | # later versions of mod_jk, and is needed for | # for load balancing to work properly | # Note: Replaced JkShmFile logs/jk.shm due to SELinux issues.
